Dude, you left yourself wide open.
You still haven't mentioned the content of what you will be shooting: B/G, bukkake, Gay, what? What the fuck are you shooting, you'll get a lot more positive responses.
What's the pay rate? How long will I need to be there? Just one scene or all day? Where is the production located? I'm certainly not flying to Bumfuck, Illinois for a single shoot.

The complete and total lack of information on your job offer and the use of a web mail account for responses is purely amateur and you deserved every piece of shit you got.

Next time, rub the brain cells together long enough to generate the heat necessary for a coherent thought. What the fuck did you expect?
